y CORE EXTRACTOR OR SAMPLER Filed Aug. 14, 1934 Patented Dec. 10, 1935 yUNITED STATES PATENT OFFICE 4 Claims.

This invention relates to improvements in core extractors or samplers designed for producing and removing a core sample from products of a resinous nature such as resin in a barrel, metal drum, r package of any material or size. It can also be used for extracting a core or sample from gums of any nature or material having the characteristics of resinous gums, that is, gums solidified from the liquid state and having a brittle or semi-solid consistency.

One of the `objects of the invention is to provide a method and means by which a core may be formed in a mass of material of resinous nature and which core may be readily removed for4 sampling purposes.

Another object is to furnish a core extracting means of simple and inexpensive construction and one which will be especially efficient in practice.

A still further object is to supply a core extractor comprising a spiral cutting means combined with a container in which a portion of the core may be retained if desired.

With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.

In the drawing:

Fig. 1 is a sectional view of a portion of a receptacle containing resin or the like and showing one form of my improved core extractor.

Fig. 2 is a similar view of a modification.

Fig. 3 isa perspective View partly in section of the extractor.

Fig. 4 is another perspective view of the extractor with the major portion of the spiral cutter removed.

Referring to the embodiment of the invention illustrated in Figs. 1, 3 and 4 of the drawing, 5 indicates a wall or top of a barrel or the like containing resinous gum 6. A port 'I cut in the wall of the receptacle permits the improved sampler to be'inserted before the receptacle is lled with resinous material or the like. The port is closed by a removable plug 8 that is connected to a wire hook 9 forming one extremity of a spiral cutter IU. This cutter is preferably formed of a coiled piece of wire wound into cylindrical form and the inner extremity of the wire as shown at I I is vbent into the circle forming the last loop so that it will function as an anchor.

Within the coil I may arrange a metal box I2 having apertures I3 and I4 in its ends to allow the contents of the receptacle to ow into the box I2.

The inner end of the box abuts against the extremity II of the coil and the outer end is held in position by a cross strap I having its extremi- 5 ties hooked on to the outer convolution of the coil.

1n operating this form of sampler, it will be obvious that when the resinous substance or the like is placed in the barrel or other receptacle 10 in liquid condition, it will flow through the coil and also into the box I2 and will subsequently solidify. Afterwards when the receptacle reaches a point of inspection, the lug 8 can be removed and as it moves outwardly its hooked end 9 will 15 come out with the plug. Now, if the plug is pulled away from the receptacle, the coil in unwinding will function as a cutter so that a core will be formed about the box I2. This core and the box can now be readily broken away from the bulk of the material in the receptacle. After the core and box are removed, of course, the box can be readily detached from the core if desired.

A simpler form of the invention is illustrated in Fig. 2 and it may be used where a core only is 25 desired without obtaining a sample in the box I 2. In this instance the coil Illa. is exactly the same as that shown in the other figures and its outer extremity 9u. is hooked to the plug 8a. When the plug and coil are removed in this case, a core will be formed without the core containing a box, like I2 in the other figures.

From the foregoing it is believed that the improved core extractor and the method to be practiced thereby may be readily understood by those skilled in the art, and it is obvious that changes may be made in the details disclosed without departing from the spirit of the invention as expressed in the claims.

What I claim and desire to secure by letters Patent is:

l. A sampler of the character described com-- rising a plug adapted to close a hole in a receptacle containing material of a resinous nature, and a wire coil adapted to extend through said hole into the material in the receptacle, said coil having its outer end secured to said plug.

2. A sampler of the character described comprising a plug adapted to close a hole in a receptacle containing material of a resinous nature, and a wire coil adapted to extend through said hole into the material in the receptacle, said coil having its outer end secured to said plug, the inner end of the coil projecting inwardly toward the axis of the coll.

3. A sampler of the character described comprising a plug adapted to close a hole in a receptacle containing material of a resinous nature, and a Wire coil adapted to extend through said hole into the material in the receptacle, said coil having its outer end secured to said plug, and an apertured box positioned within the coil.

4. A sampler of the character described comprising a plug adapted to close a hole in a re ceptacle containing material of a resinous nature, and a Wire coil adapted to extend through said hole into the material in the receptacle, said coil having its outer end secured to said plug, an apertured box positioned within the coil, and means for securing the box within the coil.
